Re: 7667 issues; black screen/ X windows crashing
I'm not clear how your problem directly relates to the previous entries in this thread, however I have a few questions:
0) Does this reproduce with a 'vanilla' 188.8.131.52 kernel without PREEMPT?
1) What kind of motherboard and BIOS version are you using?
2) I don't see anything in the bug report that appears to correlate to a system hang. Please generate a bug report immediately during or after this problem occurs (and before starting X again).
